인프런 커뮤니티 질문&답변

Address 필드가 Response 시 빈 객체로 나옵니다.

log를 찍어 봤는데 아래와 같이 dto에 address는 잘 들어가있습니다.

2022-06-26 00:43:11.618  INFO 4953 --- [nio-8080-exec-2] j.jpashop.api.OrderSimpleApiController   : dto address = Address(city=서울, street=1, zipcode=1111)

2022-06-26 00:43:11.618  INFO 4953 --- [nio-8080-exec-2] j.jpashop.api.OrderSimpleApiController   : dto address = Address(city=진주, street=2, zipcode=2222)

뭐가 문제일까요 ㅠㅠㅠ
